Abstract

The utility model relates to a novel road obstacle clearing-away vehicle which is added with an ancillary supporting small wheel. The road obstacle clearing-away vehicle is formed by that the end of the original road obstacle clearing-away vehicle is hinged with an L-shaped beam; the beam is respectively provided with a pulley wheel, a longitudinal beam telescopic oil cylinder, a supporting wheel operating oil cylinder and a concave seat; the outer side of a lower longitudinal beam is welded with a slide block outer guide sleeve; the outer guide sleeve is provided with a guide way; the guide way is provided with the collecting and the releasing slide blocks of the supporting wheel; the supporting small wheel is fixedly arranged on the collecting and the releasing slide blocks. The utility model solves the problem that the bearing load of the front and the back of the original towing vehicle are nonuniform, and meanwhile, the utility model widens the towing range of the original towing vehicle.

Description

New-type highway wrecker

The utility model relates to a kind of new-type highway wrecker, exactly is a kind of highway wrecker that adds the supplemental support steamboat.

At present, widely used highway wrecker all is made up of a tractor truck and a cantilever lifting device basically, and the front end of this device is hinged on the tractor truck, the cantilever beam external part then is used for lifting the front-wheel of the damaged automobile in accident back, so that damaged automobile is dragged away.The subject matter that such highway wrecker exists is: hang because the front axle of damaged automobile is pulled car, so make traction rear axle load increase and front axle axle load minimizing.If pull heavier damaged automobile, the serious overload of tractor truck rear axle will appear and front axle adhesive ability over the ground reduces, causes the malfunctioning situation of tractor truck handling maneuver.For the temporal method of avoiding this situation to take place often to take is to install counterweight additional on the tractor truck front axle.But this measure makes wrecker increase the weight of front axle again when zero load and then wearing and tearing are strengthened.

The purpose of this utility model is exactly according to the shortcoming in the problems referred to above, for people provide a kind of new-type highway wrecker, and then solves the problem of the unbalance stress of former wrecker.

The utility model is made up of tractor truck 1, hoisting mechanism 2, arm 4, elevating ram 5, L shaped beam 21, support steamboat 14, vertical shaft 9, following longeron girder 24, concave surface seat 28 etc.; Rear end in the chassis frame of tractor truck 1, hinged one with the front cross rail 21 rigidity bonded assembly vertical shaft sleeve pipes 9 of L shaped beam, the lifting of L shaped beam and landing are to be undertaken by elevating ram 5, and elevating ram 5 one ends are hinged on the chassis frame of tractor truck, and the other end is hinged on the vertical shaft sleeve pipe 9; At L shaped beam crossbeam 21 midways location one pulley 10 is installed, middle symmetric position is installed two following longeron telescopic oil cylinders 23 respectively in turn, longeron girder 24, support wheel are handled oil cylinder 16 down, the two ends symmetry of L shaped beam after cross member 27 is installed two concave surface seats, the outside at following longeron girder 24, welding slide block outer bush 25, be shaped on the guide track that makes support wheel retractable slide block half-twist on its outer bush 25, support wheel retractable sliding 11 is installed on its track, it is hinged that its end and support wheel are handled oil cylinder 16, and the other end is captiveed joint with support steamboat 14.When oil cylinder 16 is flexible, support steamboat 14 and change ownly with the motion of slide block 11 ground-surface angle, making it not only can be parallel to the ground, but also can be perpendicular to ground.When we tow the roadblock car, can regain elevating ram 5 earlier, make concave surface seat 28 exchange premium ground, towing hook 12 is hooked on the preceding string of roadblock car then, makes two front-wheels of roadblock car enter the concave surface seat, allow elevating ram 5 stretch out, L shaped beam is lifted, and at this moment, the propons of roadblock car also will be lifted.Make support wheel handle oil cylinder 16 again and stretch out, even support steamboat by becoming position perpendicular to the ground with the ground level position; The elevating ram 5 that moves again stops action after making the support steamboat bear certain load.Start tractor truck 1 this moment makes and the roadblock car can be dragged away.

After the utility model is realized, basically the forward and backward bearing that has solved former tractor truck carries uneven problem, simultaneously also widened pull-in range, automobile-used this car of some large-tonnage roadblock also can be dragged away, advantages such as the utility model is reliable in addition, simple in structure, easy operation.

Below in conjunction with accompanying drawing the utility model is further specified:

Fig. 1 is an integral structure front view of the present utility model;

Fig. 2 is an integral structure birds-eye view of the present utility model;

Fig. 3 is support steamboat horizontality of the present utility model and plumbness scheme drawing;

Fig. 4 is a slide block outer bush track scheme drawing of the present utility model.

1-tractor truck among the figure, 2-towing hook, 3-steel rope, the 4-arm, 5-elevating ram, 6-7-pulley, the 8-vertical shaft, 9-vertical shaft sleeve pipe, 10-pulley, the 11-bogie wheel is received, put slide block, 12-towing hook, 13-cam shaft groove, 14-supports steamboat, the 15-cam follower, and the 16-support wheel is handled oil cylinder, the 17-hinge, 18-lifting cylinder hinge, 19-vertical shaft sleeve pipe hinge, the 20-oil motor, 21-L ellbeam front cross rail, 22-back-up ring, longeron telescopic oil cylinder under the 23-, longeron girder under the 24-, 25-slide block outer bush, longeron telescopic girder under the 26-, 27-L ellbeam after cross member, 28-concave surface seat, the 29-suspension ring, 30-hinge, 31-slideway.

Tractor truck 1 should be selected the CA155 type for use, and hoisting mechanism is then selected for use and can be drawn 20 tons motor, and wirerope diameter is 11.5mm, and supporting steamboat 14 models are 7.5-20, and the pressure that support wheel is handled oil cylinder is 160Kg/cm ², φ=150mm in the slide block outer bush, thick 15mm, track slideway road is wide to be 4～10cm, and L type crossbeam is a box-structure 200 * 300 * 2300, and L type longeron adopts box girder 150 * 250 * 1800; Between cam follower 15 and the support wheel retractable piece is to captive joint, between concave surface seat 28 and the L shaped beam after cross member, down all be to weld between longeron girder and the L shaped beam front cross rail, between elevating ram 5 and the vertical shaft sleeve pipe, all be hinged between vertical shaft sleeve pipe and the traction vehicle frame; Also answer field adjustable after installing by Fig. 1-Fig. 4 structure, should note the whether leakage of oil of each Hydraulic Elements during debugging, and whether oil pressure can reach operation pressure.
